"It's hard. You don't really know the trajectory of everything and how you're going to feel mentally, physically. All you can do is really just each year evaluate it and kind of go from there.
"But, I think that when you get to this point, you understand that's more of a reality with every year you play. And you understand that. But I think you just kind of check in with that through the year, or every year, and evaluate it. So that's how I look at it.
"But I feel really good. I'm excited about going to training camp as I was my first year. So, I think the passion and that sort of thing is all there. As long as that's there, then you're willing to put in the work and do everything that it takes to be successful, and hopefully it can be at least a few more." -Sidney Crosby
